Three commonly used OSV definitions
Offshore Service Vessel → covers entire mobile offshore fleet
Offshore Support Vessel → sub-set of Offshore Service Vessels
Offshore Supply Vessel → sub-set of Offshore Support Vessels
Three basic categories of Offshore Service Vessels (breakdown of
mobile offshore fleet into segments)
Development (exploration & field development)
Production
Support
Mainly related to oil & gas, but also applicable to other offshore activities
including offshore wind energy and subsea mining
Depending on type of segment and unit, classification of Offshore
Service Vessels may involve Ship Rules, Offshore Rules, or both
OSV: what do you mean?

World mobile offshore fleet evolution
9 IDEC 2014 – Mumbai, 21th May 2014
Investment focus on large and sophisticated OSVs with deep water
capabilities in line with offshore oil & gas E&P CAPEX trend → Strong fleet growth for MODU, accommodation vessel, MPSV/DSV/IMR and
large PSV segments (orderbook/fleet ratio over 10%)
OSV chartering focus on risk management and fuel consumption → Demand for young and energy efficient vessels with high DP capability and
redundancy
Finding the right balance between commonality (multi-role/purpose
vessels) and specificity (e.g. subsea capabilities, area specific
requirements) → Operational flexibility/efficiency vs. capability
Developments in OSV design & operation
10 IDEC 2014 – Mumbai, 21th May 2014
New OSV designs for reduced fuel consumption and air emissions
Diesel-electric & hybrid propulsion systems
Application of variable frequency drives
LNG as fuel
DC grid for electrical power distribution
Icebreaking OSV for operations in ice and cold climate
Shallow draught IMSVs for North Caspian Sea (low salinity first year ice)
Fully winterised OSVs for ice breaking/management operations in arctic waters
Developments in OSV design & operation
12 IDEC 2014 – Mumbai, 21th May 2014
A broad variety of international Conventions, Codes and Guidelines
OSV regulatory relationship status: It’s Complicated
Regulatory issues:
Difference in status and degree of flag state ratification between conventions
and various OSV related guidelines
Gaps in coverage of safety critical operations in international regulations
Lack of compatibility between requirements of different international regulations
(e.g. subdivision/damage stability, fire safety & life saving appliances)
Industry develops (much) faster than regulations…
13 IDEC 2014 – Mumbai, 21th May 2014
How to ensure uniform application of consistent safety and
environmental protection standards for OSVs?
Clarification of status and ratification of conventions and guidelines
→ Need for “level playing field”
Multi-purpose offshore support vessels (MPSV)
How to close existing regulatory gaps?
Anchor handling and towing (e.g. stability & deck equipment)
Offshore (heavy) lifting (e.g. stability, crane certification & deck equipment)
Carriage and transfer of industrial personnel on OSVs
How to position OSVs relative to other ship types?
Carriage of hazardous noxious liquid substances in bulk
→ OSV vs. chemical tanker
Carriage of (industrial) personnel
→ OSV vs. passenger ship
OSV regulatory development questions
14 IDEC 2014 – Mumbai, 21th May 2014
IMO Correspondence Group on Intact Stability follows up on outcome of

16 IDEC 2014 – Mumbai, 21th May 2014
Working Group on carriage of more than 12 industrial personnel on
board vessels engaged on international voyages under IMO’s SDC
Sub-Committee
Development of definition of industrial personnel due to lack of reference in
existing IMO instruments (SOLAS, MODU Code, OSV Code, SPS Code)
→ All persons other than passengers and crew who are transported or
accommodated [on an OSV] for the purpose of offshore industrial activities
(key words: able bodied, safety training, knowledge of ship layout and safety
equipment, personal safety equipment)
Next step: development of regulatory framework
→ Reference to IMO draft guidelines for wind

Safety guidelines for tugs
Definition of class notations (service notations and additional service
features) based on realistic operational profiles and duties of tugs
Basic philosophy is that the combined system of tug and assisted vessel
should be assessed in a holistic manner
Technical requirements are a function of the selected class notation(s)
Definition of design loads for towing, escorting and pushing
Towing and escort stability
Towing and escort equipment (strength and safety)
Safety equipment (fire safety, life saving
appliances, radio installation and navigation
equipment for non-Convention tugs; anchor
equipment for all tugs)
Guidance for interaction between tug and
assisted ship (communication, towing
fittings, pushing areas and making fast)
