Sustainability Report 2014
Climate Change & Emissions to Air
The board of directors has the responsibility for climate change within the DOF Group and that The DOF Group is committed to ensuring that its activities shall have minimal impact upon the environment.
The DOF Group Environmental Impact Policy reflects corporate intentions, principles of actions and aspirations with respect to improving Group Environmental performance. The Environmental Impact Policy is the Group’s highest level environmental document and frames the approach of the BMS in respect to managing our environmental interactions and setting strategic environmental objectives.
Defining and measuring environmental sustainability risks associated with business activities is an important activity for the DOF Group. Since 2010, the Group has reported key environmental performance through the Carbon Disclosure Project (CDP) and the reporting has directly influenced the development of our Business Management System and the programs established to manage our environmental performance.
In terms of GRI reporting for this material aspect our data has been public and predates the 2014 GRI start date, since we have been reporting to the Carbon Disclosure Project for the first time in 2010.
The CDP and the GRI G4 specific standard disclosures criteria for energy, emissions and compliance are closely aligned.
DOF group have an overall target to reduce fuel consumption in our fleet with 10% compared to operational days per vessel within a period of 3 to 5 years. The reason for having a target based on operational days is that DOF have a growth strategy. CO2, SOx and NOx are gasses which is part of the exhaust from combustion engines, with reducing the fuel consumption we will reduce the emission of these gasses. In addition to several measures for fuel reduction DOF have invested in equipment to reduce NOx emission.
Business Management System Overview
The DOF Group Business Management System operates in line with OHSAS 18001:2007, ISO 14001:2004, and ISO 9001:2008.
ISO: 14001:2004 provides the Business Management System with the basic elements required to achieve continual development in Group environmental performance. The basic elements of ISO 14001:2004 have been integrated into the management system in a way that ensures activities we remain compliant to the accompanying ISO 9001:2008 and OSHAS 18001:2007 accreditation ce rtificates and client requirements. The business management system also takes into account industry bodies, guidelines, codes of practice and best practice techniques at international, regional and local levels.
Managing Fuel Consumption and Emissions to Air
GRI-G4-14 | GRI-G4-EN3
Participating among 260 Nordic companies in the CDP, the Group achieved a score of 89 C in the reporting year 2013. This is a significant positive shift of 37% improvement on the previous score of 65 D reported in 2012.
Our efforts toward achieving an improved score have increased our internal competence level and awareness on environmental issues. The Environmental Impact Policy sets out clear aspirations for ensuring that our operations have a minimal impact on the environment. This requires the DOF Group to caclulate and anticipate potential challenges before activities take place through risk identification processes, to ensure that the environmental impacts are understood and reflected in our activities.
Our Environmental Management System (EMS) ensures that the Group effectively manages our operations and strives for continual improvement of our environmental performance. There have been no severe spills to the external environment recorded during the Group’s history.
The Group has a modern fleet and several of the vessels are fitted with technology reducing fuel consumption and emissions. The diesel electric hybrid propulsion system allows greater operational flexibility and reduces energy consumption, CO2 emissions and maintenance costs. This propulsion system is ideal for the Group’s combined anchor handlers and offshore construction vessels. Improvements, particularly on hull design, have been made through close industrial cooperation with main suppliers. This experience transfer is vital in continuing enhancement of technology into the future.
A vital part of our EMS is the Ship Energy Efficiency Management Plan (SEEMP). Developed in partnership with DNV GL and aligned to the guidelines set out by the IMO marine environmental protection committee; SEEMP was implemented in 2012 for the entire Group’s fleet to plan, implement and monitor measures required to maximize vessel efficiency.
Based on the experience from SEEMP, the Group will increase focus on competence building offshore to ensure efficient use of the technology implemented on board our vessels.
Through continued focus on technologically advanced vessels and an improved environmental culture on all levels of our organisation, we will achieve our objective of a reduction in CO2 emissions, through reduced fuel consumption.
All DOF’s vessels operate with Marine Gas oil – MGO, which is an ultra-low sulphur fuel. This makes DOF compliant with the regulations in the industry, especially with IMO and MARPOL Annex IV, Regulation 14, regarding strict measures addressed to shipowners to control the emissions of NOx and SOx from their ships, in Emission Control Areas (ECA).
DOF have since 2007 had focus on reducing NOx emission to air. Main contributor is installment of Selective Catalytic Reductions (SCR) systems which can reduce NOx emission with up to 90%. SCR is a mean of converting NOx with the aid of catalyst urea into N2 and Water. See figure 6.6.
Skandi Gamma can also operate with Liquified natural gas – LNG, and Skandi Vega can benefit from the use of onshore power supply (OPS) which means that she can shut down the engines whilst moored and connect to shore side power to run all the functions on board.
The environmental benefits of utilizing renewable energy are considerable, since carbon dioxide, sulphur dioxide and nitrogen oxide emissions are reduced to a minimum.
For DOF, all those environmental friendly initiatives are also of great importance towards the achievement of its sustainability goals, above all, to have a reduction of 10% in fuel consumption within the next 3 - 5 years.
DOF’s internal procedures concerning bunker and fuel testing ensure control of fuel supplies to its vessels with the main objective to ensure good quality and uncontaminated fuel supplies to the offshore installations in accordance with Charterer requirements. All the contracts between DOF Management and charterer specifies the quality of the fuel as specified by ISO 8217, Bunker Fuel Standard.

Carbon Dioxide Emissions
– Scope 1 and Scope 2
GRI-G4-EN15 | GRI-G4-EN16
Data regarding Scope 1 concerns fuel vessel consumption for all DOF vessels (including third party vessels).
Scope 2 data relates to electricity and heat consumption in buildings where DOF has offices or warehouses.
The target is to increase the amount of operational days with a relative reduction in CO2 emissions per day in operation. This aligns with DOF group growth strategy with increased vessel utilization and increased fleet size. The aim is to reduce the emissions and fuel consumption by 10% from 2013 (base year) to 2018.
