This order further demonstrates Toisa’s commitment to the future of the deep water construction
markets. These are markets in which we already operate a number of modern vessels but where we
recognise that the future needs of the offshore industry cannot be fully met from the existing, and
aging, world fleet.

This large, capable, flexible unit has the potential to be further customized to individual client
requirements and will represent a significant enhanced addition to Toisa’s existing construction
vessel fleet.

This vessel can, and will, support a wide variety of subsea operations world‐wide. This order will
provide the market with a DP3 vessel where full compliance with the SPS Code is a fundamental
principle of the design and also includes arrangements to meet DNV’s COMFORT Class.

The vessel has all the inherent flexibility in design of previous Toisa construction vessels ‐ and more
so. The under‐deck configuration provides space allowing installation of 2 x 2500 Tonne capacity
under‐deck carousels, and/or a range of alternative equipment to be installed – similarly, a large
deck area of c. 2900m2 is optimised clear space for the installation of project equipment such as
pipelay spreads and the carriage and deployment of heavy offshore equipment for installation.
A fully integrated vessel management and control system of all key functions is fitted on the vessel
and includes the optional provision for deployment of a deck mounted diving bell through a central

The now common requirement for subsea construction vessels to accommodate large numbers of
contractors personnel has also been addressed in designing the ship to accommodate up to 250
persons ( depending on Charterers requirements).

Sealion Shipping Ltd currently operates four existing Construction vessels within its varied modern
fleet of twenty five offshore support vessels. In addition, Toisa has a further five offshore support
vessels presently under construction, that will join the Sealion fleet during 2013 and 2014. Further
newbuilding projects remain under consideration.

Allseas gets another Deepwater Construction Vessel
The Fortitude is now on its way from China to Europe with on deck the tub for the new 5,000 Tons Huisman Crane for the Pioneering Spirit.

2 April 2018

Early last month Allseas acquired the Deepwater Construction Vessel ex Toisa Patroklos, built at the Hyundai Yard in Korea in 2015 and renamed here: "Fortitude". With the downturn in Offshore related work for the Toisa Group, the recently built Toisa Patroklos was sold last month to the Allseas group.

The new vessel will dominantly work as an Offshore Support Vessel for Allseas' flagship the "Pioneering Spirit, which is fully booked with work. Now working on the first part of the Turkstream pipeline across the Black Sea, the Pioneering Spirit will then be heading to Norway for it's first installation Project: Johan Castberg Topside this summer. Then the second part of Turkstream will be completed. End this year the 5000 Tons Huisman Offshore Crane will be installed at PS aft of the Pioneering Spirit.

With three MacGreogor Knuckleboom cranes on deck and the Ulstein X-Bow design, it is a well selected choice to support the Allseas fleet of sophisticated pipe-lay vessels.

The specifications of the vessel are:

Vessel type: Offshore Supply Ship
Gross tonnage: 30,000 tons
Summer DWT: 12,500 tons
Length: 150 m
Beam: 32 m
Draught: 7.4 m

MacGregor: 900 Tons Knuckle boom down to 3500 m waterdepth
MacGregor: 200 Tons Knucke boom crane to 2000 m waterdepth
MacGregor: 2x20 Tons service cranes
