- Development of the required engineering technical documents and a supporting Project approved by the Engineering Official Boards at Vizcaya and Barcelona.
Enlargement of STSs (years 2004, 2005, 2006 and 2007)
Enlargement is the action of enlarging one or more geometrical characteristics of an existing crane, allowing operation under conditions which were previously impossible.
Although enlargement is mostly related to structure, in most cases it implies redesigning the associate mechanisms.
Crane enlargement is a smart and profitable response to the obvious need of adapting existing cranes to the dimension and operation requirements of frontline vessels and to the demand for a better use of space in the container storage area.
We can offer the necessary technical means and experience to perform enlargement of STS and RTGs, including design and calculation of adjustments to be introduced and their adaptation to the existing structure.
The following projects can be listed as part of our experience:
2.5 meter enlargement of 4 Paceco RTGs (Trastainers) in OPCSA (Las Palmas) to increase working height in one container.
2.5 meter enlargement of 26 RTGs (Trastainers) manufactured by Paceco, Noell and ZPMC in MAERSK (Algeciras) to increase working height in one container.
5 meter-high enlargement and 6.5 meter scope enlargement in two STSs (Portainers) in TCV.
5 meter-high enlargement in other 2 STSs (Portainers) in TCV.


For these projects, the applicable engineering technical documents were submitted, as well as the supporting Project approved by the Engineering Official Boards at Vizcaya, Las Palmas and Valencia.
Additionally, the certificates and necessary documents were developed to help the customer obtain the EC. Certification after the crane adjustments.
Complete Assembly of STSs.
Since the first days of MAREIPORT, we have performed complete assembly of RTGs (Trastainers) and STSs (Portainers), including transportation to dock rails of the latter for different manufacturers (PACECO, LIEBHERR, KONECRANES, FANTUZZI, IMPSA...) in nearly all container terminals on the Mediterranean and the Canary Islands (TCB, TERCAT, MARVALSA, TCV, MAERSK, OPCSA, CAPSA, CASTELLON, LA LUZ ...)




MARVALSA Container Terminal - Valencia (Spain)
Accident Assistance
Our activities also involve providing the necessary technical assistance to our Customers in case of crane accidents, performing disassembly tasks on collapsed structures (“rescue” work) and securing the accident area.
As an example of our experience we can mention:
- 25-ton mobile-frame spinning gantry crane in IZAR FERROL. (Year 2001)
- Two 130-ton mobile-frame spinning gantry cranes and one 75-ton mobile-frame spinning gantry cranes in CNN (Former IZAR SESTAO). (Year 2006)
- Accident at MARVALSA in 1995 involving 3 Portainers
- Assistance in “minor” accidents involving crane jibs, winches and crane supports for container carrier cranes (Marítima Valenciana, MAERSK Algeciras, TCV,...).
- G9 Accident in MARVALSA in 2006
- Crane jib accident in TCV in 2005/2006
Reconstruction of damaged cranes
Complementing the previous activity, or independently from said activity, we can carry out reconstruction work (total or partial) on cranes damaged by accidents.
These are some of the tasks we performed in this area:
- Complete reconstruction of mobile framework (manufacture and assembly) of a 25-ton spinning gantry crane in IZAR FERROL, providing the necessary engineering technical documents and the supporting project approved by the Engineering Official Boards at Vizcaya and A Coruña (year 2001).
- Complete reconstruction of two 130-ton mobile framework cranes and one 75-ton mobile framework crane (manufacture and assembly) in CNN (Former IZAR SESTAO), providing the necessary engineering technical documents and the supporting project approved by the Engineering Official Board at Vizcaya (at present).
- Structural repairs in crane jibs, winches and crane supports for container carrier cranes (Marítima Valenciana, MAERSK Algeciras, TCV, TCB,...), including transportation of cranes to the repair area and back to dock rails.
Complete change of crane and counter jib structure downwards (supports, winches, carts…) at the Container Terminal in Puerto Cortes – HONDURAS
Crane transportation and unloading
We assist and cooperate with other companies in crane transportation, either due to relocation within the facilities or due to transportation (mounted or dismounted) to the new location where they are going to operate.

These are some examples of our past experience in this area:
- Disassembly in Algeciras (Crinavis) and subsequent assembly in Rodman Polyships (Vigo) of a mobile framework spinning gantry crane with a load capacity of 140 tons.
- Cooperation with Ale-Lastra in loading, unloading and shoring works of an STS for ship transportation from Barcelona (TCB) to the Canary Islands (CAPSA).
- Assistance for unloading ZPMc cranes in MAERSK (Algeciras).
- Transportation of all MARVALSA gantry cranes, 7 Portainers and 17 Transtainers in 1998, from Levante and Xitá docks to their present location, without interfering with port traffic or the operation of Valencia Maritime Terminal, which became the most important movement of port machinery in Europe.
- Crane movements in Algeciras in collaboration with to Ale-Lastra.

Reports and Technical Assistance
Apart from the aforementioned activities, we perform tasks related to inspections, repairs, adjustments, etc, of all types of cranes, providing the required engineering, manufacturing, quality control and work direction.
We also develop technical reports on the condition of cranes and budgets to measure their damage.


Compliance with NUREG 0554 Regulations for Cranes in Nuclear Power Stations
In the past years we have started adjusting cranes in nuclear power stations for compliance to the NUREG-0554 and NUREG-0612 regulations, section C.
These works involve adjusting the existing cranes to operate under strict single failure conditions required by virtue of said regulations.
This type of work implies a high participation of the engineering area and the development of technical documents, as well as thorough preparation of the tasks and manoeuvres to be performed, due to the great responsibility involved in handling the loads the crane will operate with.
We finished the first project of this type in 2006, which consisted in adjusting a 78-ton gantry crane (DRL) and a 75-ton gantry crane (MCL) in order to comply with NUREG-0554 and NUREG-0612 regulations section C, including the design, manufacture and assembly of a new cart for that purpose.
In summary, the project involved:
- Study and support of the gantry structure of the crane under seismic spectrum conditions called SSE.
- Design and manufacture of a new cart, including the main lifting and cart movement mechanisms.
- Study and support of the new cart structure under seismic spectrum conditions called SSE.
- Development of a project approved by the Engineering Official Boards at Vizcaya and Guadalajara, including all elements, mechanisms and structures manufactured in compliance with the NUREG regulations.
- Complete electrical update of the crane.
- Assembly of all manufactured structures and equipment, replacing the old cart in the crane. This assembly was performed without auxiliary cranes since it was carried out in the containment area, just above the reactor.
- Design and manufacture of loads and special tools for the performance load tests (static overload and dynamic load).

- Development of the required technical documents for crane certification (maintenance range for all equipment, mode analysis of failures and effects, supporting calculations in compliance with NUREG regulations…)
- Technical assistance to customers for crane certification by the Nuclear Safety Council, including an inspection of the whole project by said agency.

Dynamic Test

- Disassembly and wheel replacement in cart and gantry.
- Installation of “storm brakes” in STSs movements.
- Installation of gantry rails in docks.
- Repairs of crane frameworks, with “in situ” automation if necessary with a portable rod.
