Marine Mammal survey

MV Orca is equipped with a detachable observation tower designed specifically for Marine Mammal & Seabird Observation (MMSO), which permits a minimum eye height of 5 m above sea level. 

A stern-mounted davit/boom and detachable manual winch have been installed for the deployment and recovery of up to 500 m of Passive Acoustic Monitoring (PAM) hydrophone array cable or other oceanographic instruments. The on-board 2 KW Honda ‘whisper’ diesel generator can be used for powering environmental monitoring equipment exclusively. It has low-operational noise of just 52 dB (less than normal speech), and three-pin electrical sockets inside the cabin with sufficient power to run several laptops and associated electronics.

Marine Mammal survey

MV Thor is equipped with a uniquely-designed observation dome which can be used specifically for Marine Mammal & Seabird Observation (MMSO) with adequate eye height above sea level.

MV Thor contains liveaboard facilities for six people including galley, laundry, and showers. Deck equipment includes a one tonne deck crane, two 29 kW gensets, and a 4.7 m Humber Rigid-Hulled Inflatable Boat (RHIB) with a 40 HP outboard engine.

First constructed in 1988 as an ambulance boat, with an astonishing top speed of 44 knots, MV Thor was refitted in 2002 to be utilised as a fast patrol boat and Royal Air Force (RAF) training boat. Since construction, she has been extended by 4 m and is currently fitted with 2 x Detroit diesel 1410 w engines. MV Thor is scheduled for a further refit to prepare her for a more environmental research and surveying purpose. Progress updates will be made available as her refit continues.

Third-Party Charter Vessels

OSC periodically hires charter vessels for survey work. Charter operators and companies are invited to submit their details, where vessels meet the desired specifications to support any of our range of services for both coastal and offshore projects.

WiSe Operator

OSC personnel are qualified to operate fast crafts and small vessels, for which they have received WIldlif SafE (WiSe) training and accreditation (‘Accredited Marine Industry Operator’), a scheme designed to promote universal protocol for safe navigation of boats in the vicinity of macro marine wildlife (e.g. cetaceans, pinnipeds, sharks and turtles) and minimise any disturbance to these animals. WiSe is a self-regulatory scheme that is entirely funded by the UK government and receives the logistical support of many mainstream international NGOs.
