SENER develops a Multipurpose Subsea Support Vessel

The operators are demanding more efficient, less consuming and more capable vessels while the shipbuilders need to achieve it in a very competitive environment. SENER, as a ship design firm, play an important role offering value to all stakeholders, with innovative designs taking in consideration all the requirements already mentioned.

Currently, SENER is developing a new Multipurpose Subsea Support Vessel specially designed for subsea ROV (Remoted Operated Vehicle) light construction duties, for world-wide service. The ship will have a length overall of more than 112 m, a length between perpendiculars longer than 100 m and a breadth of 22 m. The depth to main deck will be of 9 m while the draft will have more than 7 m. In total, it will be able to accommodate 110 persons on board.

The vessel will incorporate the following capacities: two FP (Fixed Pitch) Azimuthal main propellers of Diesel electric propulsion, two FP tunnel thrusters and one FP retractable Azimuthal thruster. It will contain a 40 MT (metric Tones) electric deck crane, with option for a bigger one (250 MT), and will be able to work in 4,000 m depth. It will have an integrated moonpool of 7.2 x 7.2 m and a helicopter deck. Besides, the main deck will be reinforced for heavy weights. The design has also prepared the ship for an optional 600 t cable carousel.

Besides of having designed several types of vessels along their more than 50 years of dedication to ship design and marine engineering activities, during the last ten years SENER has been widely involved in tugs and offshore vessels. The experience and know how in this shipbuilding segment has promoted SENER´s participation in several relevant projects over the world.

SENER has recently developed Stern Drive Tugs (Ona Don Lorenzo for Tras-Ona, Argentina and VB Bravo, VB Campeador and VB Corsario for Boluda, Spain), Voith Tractors (Tommaso Onorato for Moby S.P.A., Italy, Solan and Bonxie for the Shetland Island Council, Scotland and 40, 41, 42 and 43 for the Antwerp Port Authority, Belgium) and Rescue Tugs (María de Maeztu, María Zambrano, María Pita, Marta Mata, SAR Mastelero, SAR Gavia and SAR Mesana for SASEMAR, Spain) and has developed its own design of LNG propulsion tug, in collaboration with Main Engine makers and Bureau Veritas.

Finally, it is relevant the double role of SENER as ship design firm and developer of the FORAN CAD/CAM System. With this, SENER gives more value to their clients, leveraging its knowledge in ship design and thus improving its software capabilities. Taking advantage of this double role, SENER has updated the Naval Architecture modules of FORAN, the version V70R3.0 is the launching of FBASIC module that will replace the former modules of Naval Architecture Calculations and incorporates new features to make easy the generation of documents, to perform calculations, and can be easily installed on board the vessels to be used as Load Calculator, with all the information of the vessel already included if the design has been made using FORAN. This functionality is being tested to be used onboard Anchor Handling Tug and Supply Vessels.
