Flyndre and Cawdor Environmental Statement Section 3 Environmental Baseline vessels. The development will help maintain employment in local services and provide valuable monies into the economy. 3.6.2. ECONOMIC IMPACTS The Flyndre and Cawdor fields will commence production in Q3 2013 and Q4 2014 respectively with production planned to continue to the end of July 2028 at both fields. During this time approximately 41 and 23 million tonnes of oil and approximately 11 and 15 million Mm3 of gas will be produced from the Flyndre and Cawdor fields respectively. This will have a positive effect on both reducing UK imports of hydrocarbons and in providing revenue to the Exchequer. 3.6.3. FISHING ACTIVITY One of the main areas of potential adverse impacts associated with the development of the offshore oil and gas industry is in relation to fishing activities. Offshore structures have the potential to interfere with fishing activities as their physical presence may obstruct access to fishing grounds. Knowledge of fishing activities and the location of the major fishing grounds is therefore an important consideration when evaluating any potential environmental impacts from offshore developments. In terms of marine ecosystems, ICES (International Council for Exploration of the Sea) is the primary source of scientific advice to the governments and international regulatory bodies that manage the North Atlantic Ocean and adjacent seas. For management purposes ICES collates fisheries information for individual rectangles measuring 30 nm by 30 nm. Each ICES rectangle covers one half of one Quadrant i.e. 15 license blocks. The importance of an area to the fishing industry is assessed by measuring the fishing effort which may be defined as; the number of days (time) X fleet capacity (tonnage and engine power). Due to the requirement by UK fishermen to report catch information such as total landings (includes species type and tonnage of each), location of hauls and catch method (type of gear/duration of fishing), it is possible to get an idea of the value of an area (ICES rectangle) to the UK fishing industry. The proposed development spreads across two ICES rectangles (42F1 and 42F2). Within these areas the UK fishing effort (Table 3‐14) varies throughout the year but annually can be considered low in comparison to other ICES rectangles where fishing effort can be as high as 20,000 hours per year.

As can be seen from Figure 3‐11, landings from ICES rectangle 42F1 are primarily made up of demersal (e.g. cod, haddock, hake, monkfish etc.) and shellfish species (primarily nephrops with

SHIPPING Shipping traffic within the SEA2 area of the North Sea is relatively moderate, with an average of between 1 and 10 vessels per day on routes passing through these waters. The majority of shipping traffic comprises ships, supply vessels and tankers (Cordah, 2001). Merchant vessels account for over 61% of vessels within the CNS with 45% of these vessels falling within the weight class of 0‐1499 dwt. Supply vessel routes originate in Aberdeen or Peterhead. A number of tanker routes exist within the SEA 2 region, the majority of which are orientated along a north/south heading. All tankers within the area weigh in excess of 40,000 dwt (Cordah, 2001). Table 3‐15 shows the shipping classifications for the CNS. Shipping Type No. Routes Total No. Vessels Weight Class (dwt metric t) Merchant vessels 14 14,169 0‐1,499 Supply vessels 20 8,564 0‐1,499 Tankers 7 400 >40,000 Table 3‐15 Shipping classifications for the Central North Sea (Cordah, 2001). Within the area of the development shipping density is considered very low (DECC, 2010). A shipping collision risk assessment will be carried out prior to any of the Cawdor wells being drilled. 3.6.5. OIL AND GAS The proposed development is within a well developed oil and gas area of the North Sea (Figure 3‐12). The closest surface infrastructure to the development is the Maersk operated Janice FSPO which is approximately 6.5 km south‐south‐west of the Clyde platform while the Talisman operated Fulmar AD platform is approximately 9.5 km north‐west form the Clyde platform.
