WTIV Class and Statutory Regime

11

Jack-up? Cargo ship? Special Purpose ship?

• No mutual approach for certification amongst the Flag states

• Commonly MODU-Code and SPS-Code applied simultaneously

: ?

Class: fit for purpose Rules developed from Heavy Lift ships and Jack-ups

Statutory:


WTIV Classification Regime – cont’d

12

Decision about slider position currently

prerogative of the competent Flag State

As clear IMO guidance is currently missing, early consultations between all

involved parties required (owner, yard, class, flag)

Meanwhile DNV GL supports owners / yards finding the most suitable regulatory

approach for maximized availability of their particular vessel and obtaining flag

state agreement of this approach

WIND FARM SERVICE VESSELS or CREW TRANSFER VESSELS (CTV)

15

• Windfarm service vessels (typical smaller service crafts), are on the range 20m to 40m length.

• There is a large number of these vessels classed

by DNV GL, ranging from catamarans over SWATHs to trimarans. Typically in aluminum, high speed.

• Typically used for day transfer or day service.


WIND FARM Service Operation Vessels (SOV)

16


WIND FARM SOV FLEET

SOVs are recent trend in Europe for larger, dedicated, fit for purpose “mother

vessels” to service wind farms w/ technicians living on board, using special

gangway systems and some having helideck, typically 60+ people onboard (in

addition to crew)

All 6 current operating and 4 under construction Wind Farm SOVs are classed by

DNV GL

Since 2010, over £9.5bn has been invested in offshore wind in the UK, another £18bn will be invested in projects by 2021, making offshore wind

one of the biggest infrastructure programme in the UK.
