Platform Supply Vessels, or PSV’s, specialize in the logistical support of the offshore oil field. Working betweenan onshore supply base and offshore work locations PSV’s transport essential consumables in tanks under deck (for instance drilling fluids, cement, fuel& water) and other supplies (such casing, spare parts, food &provision) on its deck. 

PSV’s can be summarized into 3 broad categories; small,medium or large, calculated based upon deadweight (i.e. their cargo carrying capacity) or cleardeck area (i.e. the space available to place cargo on deck). Below depicts the sizes in both cases:

Supply & Demand Dynamics

The demand for PSV's, and offshore service vessels (OSV's) in general continues to be driven by the world's increased energy demands. Although over the long-term global energy consumption will see a significant shift away from oil and gas, oil and gas remain a major source of consumption representing more than 50% of market share. Gas growth is expected at 1.9% p.a. and oil 0.8% p.a. through to 2035. Furthermore, it is anticipated that a greater reliance on offshore resources will be seen as onshore production declines and technologies open the door to more difficult offshore resources.

The PSV market is highly cyclical. Utilisation and rates are quick to react to oil price due to the influence oil price plays on E&P spending patterns (see Rig Count). As of mid 2018 oil prices have reached US$70 per barrel and rig count and investment has began to slowly rejuvenate. Despite this the largest challenge to owners is the huge oversupply of vessels. Because of this competition between Owners remains high and day rates low.  

Demand Outlook

PSV demand has began to increases since the 12 year lows ofUS$26/barrel. Now with oil price at circa US$70/barrel confidence begins to build in the market and once uneconomical projects are under consideration again. North America, South East Asia and Northern Europe all show huge growth potential given how far the regions declined over the proceeding years however at present growth remains stagnant and will likely continue until the market regains confidence in the current oil prices. The Middle East continues with small growth in the small to mid-size PSV tonnage due to the favourable oil economics and increasing rig activity.

Supply Outlook

Oversupply of vessels looks to be the biggest challenge vessel owners will face for the next few years. A huge supply glut following multiple years of aggressive new-build programs remains and OSV’s out number rigs 8:1 as of early 2017 (160% increase from 2008). This holds rates and utilisation down at some of the lowest levels seen.

Circa 24% of the global existing fleet is 20+years in age and not expected to work again. Unfortunately these numbers are offset by a continued new-build program estimated at 8-12% of existing OSV’s. Based on these economics vessel owners remain locked into challenging times for the foreseeable future.

Regional Heat Map

With the exception of the Middle East, most regional markets have suffered the same fate during the oil downturn. See below for a snapshot of the latest trends in each region:

Key Players

The OSV market is highly fragmented. With a global fleet of circa 3,500 vessels the top 11 owners represent just less than 32% of the market. The remainder of the market is taken up by some 400-500 vessel owners with an average fleet size of 4-5 vessels. The below chart depicts the vessel split between the main PSV & OSV suppliers.

Portfolio Positioning

Cost & Price Analysis

Due to the competitive nature of the market PSV owners are operating at close to breakeven with most owner's recording loses since the  downturn. The breakeven point of a mid to large size PSV is US$8,000 to US$10,000 per day depending on region. This is broken down as follows

Current day rate trends are as follows:

Small to Mid
Mid to Large
Low Daily Hire Rate (US$)6,0008,000
High Daily Hire Rate (US$)12,00021,000

Procurement Strategy

In the current market environment buyers are in a dominant position. The huge oversupply of Platform Supply Vessels, the regional mobility and low demand place power firmly in the buyers hands. Buyer’s should look to take advantage of this position securing cost reduction and higher specification vessels (fuel economy & safety). Where possible Buyer's should look to aggregate spend to further improve leverage. In summary the strategic objectives should be focused around:

When approaching the market DALEEL recommend the approach outlined below:

In preparation for any tender or negotiation Buyer's should ensure they have:

  • The latest market intelligence in the region including utilisation and indicative rates
  • The latest supplier intelligence including vessel availability, utilisation and rates
  • Information on other regions vessel availability and rates. Given PSV's are highly mobile Buyer's should look globally and try to take advantage of lower demand in other regions.

Technical Insights

Dynamic Positioning Explained

A DP system automatically triangulates between GPS satellites and/or other positioning systems to maintain the vessels position within a 1m to 3m radius allowing the vessels to be maneuvered very close to platforms and rigs. Check out the video below of a supply vessel operating in heavy weather in close proximity to a jack-up rig:

When engaged the DP system simultaneously and continuously controls bow thrusters and main propulsions to hold position irrespective of current, wind or wave action. This allows for greater accuracy and safety when manoeuvring removing a large portion of human error risk. DP Systems have 3 classes each representing a greater level of redundancy in the system. 

Diesel Electric Propulsion Explained

Diesel Electric Propulsion differs from traditional propulsion systems in that multiple diesel engines each drive an electrical generator producing electrical power that energizes a motor connected to the propellers. This provides efficiency (fuel & emissions) benefits as when loads are low not all diesel engines will be turned on. In addition, even where one engine fails power can still be transmitted to both shaft lines.

Performance Management

Whilst awarding a contract to the right supplier is important measuring, analysing and managing performance ensures the expectation set at the outset are achieved. Below is a snapshot of where both suppliers and buyers need to focus to ensure success as well as some indicators that help identify if you are on the right path.
