Semi Swath Research Vessel Bibby Tethra

Introduction & Technical Presentation

Introduction to Osiris Projects

∗ Established in 1997 as an independent UK company

∗ Osiris Projects provide a broad range of expertise in hydrography, engineering geophysics, marine geotechnics, engineering geology, maritime archaeology and oceanography

∗ 50+ full time professional staff

∗ 100% of turnover relates to coastal seabed survey

∗ Workload is currently split 60:40 between renewables and oil & gas

∗ Worked in offshore wind since 2001

∗ ISO 9001:2008 Quality System

∗ Documented health & safety system in line with ISO 18000

∗ One of only 4 survey contractors in Europe to hold a term contract with Shell Exploration & Production.

∗ Own and Operate 4 small coastal survey vessels including a

24hr vessel

∗ Own a range of survey equipment

∗ Unique new build 27.5m research vessel delivered May ‘11

Introduction to Osiris Projects

Vessels

9m Eagle

∗ Coastal survey - traditionally has had an unpredictable workload

∗ Short duration and close to shore, pipeline landfalls, long sea outfalls, ports & harbours

∗ Offshore, large vessels, large equipment, very expensive

∗ Niche created between the two by offshore renewables

∗ Large areas, shallow and close to shore in the case of R1 & R2

∗ Created demand for very capable coastal vessels

∗ Reduced operating costs when compared with large offshore vessels

∗ Two independent propulsion systems ∗ Precise & endless speed control ∗ Economical & efficient ∗ 1 Generator operation in survey mode ∗ Acoustically quiet ∗ Vectored thrust capability in DP operation ∗ Safe with no external moving parts

Dual Propulsion

Pump Jet Operation

An impeller sucks in water through the intake funnel, a protective grid in the bottom plate preventing foreign bodies from entering the Pump-Jet.

The impeller forces the energized water into a diffuser, as a result of which kinetic energy is converted into pressure energy.

This energy transformation process is continued in the diffuser, and the water is collected in the pressure casing.

The water is finally expelled through the outlet nozzles at an angle of 15°, and thrust is generated which can be steered through 360°.

∗ Exactly tailored to the vessel characteristics ∗ Multiple operating modes ∗ Bridge and 3 external control positions ∗ Control of thrusters and main propulsion ∗ Interfaced directly to QPS Qinsy ∗ High performance dual MRU input ∗ Automated survey line keeping modes

Precise Dynamic Positioning

∗ Ixsea Hydrins Inertial Navigation System ∗ Ixsea Octans Fibre Optic Gyro and MRU ∗ High Accuracy ∗ Mounted in Sonar room ∗ User Friendly Interface ∗ Low maintenance
