Care for the environment is one of our core values and forms an integral part of our business planning. Prosafe’s goal is zero accidental discharges to the sea and zero accidental emissions to the air, which is in line with our principles for sustainable development.
Environmental management is at the core of our Integrated Management System. By integrating environmental considerations in our risk assessments, we endeavour to minimise the impact of our day-to-day operations on the environment.
We produce Environmental Impact Assessments for each of the vessels that we operate. The assessments consider the mode of operation of the vessel together with generic geographical considerations. Local assessments are typically performed with our clients to ensure a collaborative partnership approach.
Moreover, we cooperate actively with customers and suppliers to set in-house goals, make continuous improvements to our own routines and shape attitudes towards protecting the natural environment from pollution by our operations. All accidental discharges and emissions are reported and followed up in the same way as injuries and material damage.
Reducing our ecological footprint
We are actively seeking solutions to minimise emissions to further reduce our impact upon the environment. Environmental considerations are an important aspect when planning vessel refurbishments and upgrades. We continue to actively reduce emissions by investing in more modern and fuel efficient equipment and continuous improvement in operating procedures.
Prosafe cooperates actively with clients and authorities to reduce the impact of its operations on the natural environment. An example of this is a contract where Prosafe receives incentives when the daily diesel consumption is reduced.
Prosafe continues to high-grade its fleet by scrapping the eldest and most inefficient vessels at certified ship recycling yards.
Our vessels have International Air Pollution Prevention (IAPP) certificates, International Oil Pollution Prevention (IOPP) certificates and International Sewage Pollution Prevention (ISPP) certificates.
These certificates are all issued under the International Convention for the Prevention of Pollution from Ships (MARPOL) and are subject to periodic survey.
Facilitating improvement over time
In 2009, Prosafe joined the Confederation of Norwegian Enterprise’s (NHO’s) Environmental Agreement on NOx. By signing the Agreement, Prosafe committed itself to prevent and reduce environmental problems caused by emissions of nitrogen oxides in its offshore operations.
Prosafe continued throughout 2009 and 2012 with refurbishment projects of vessels which included the replacement of older engines with low NOx engines resulting in a reduction of diesel and lub oil consumption, contributing to a reduced environmental impact. The replacement of old tonnage has resulted in five older vessels being replaced with three new built vessels throughout 2016/ 2017 with more efficient diesel engines, producing less NOx emissions.
Going forward, we will continue to gradually implement new technology and refurbish equipment in order to further reduce emissions.
Spills and emissions
Prosafe had no reportable discharges to the natural environment in 2018. We calculate the emissions of CO2, CO, NOx, SO2, CH4 and VOC for the managed fleet based on the fleet’s diesel consumption.
It is important to note that the amount of diesel consumed, and thereby also the amount of emissions, will vary largely depending on:
- the number of vessels under Prosafe’s management
- the fleet utilisation (i.e. the amount of time that the vessels have been operating)
- the vessels’ operation mode – dynamically positioned (DP) vessels maintain their position by means of thrusters and will therefore use far more fuel, and thereby also have substantially higher emissions, than vessels that maintain station by moorings
The number of vessels that use DP and the number of days that these vessels keep their position by using DP can vary from year to year.
The calculated emission data for vessels operated by Prosafe:
|Calculated 2018 total (tonnes)||Calculated 2017 total (tonnes)||Calculated 2016 total (tonnes)||Calculated 2015 total (tonnes)||Calculated 2014 total (tonnes)|
We actively monitor and manage staff travel, reporting on CO2 emissions globally.
Prosafe operates to an approved chemicals list that is based on a risk assessment matrix and hierarchy of controls.
All chemical and hazardous substances are subject to an evaluation which identifies a ‘Hazard Categorisation’ having taken into consideration the impact and effect the substance may have on health and the natural environment. Substances are assigned either a High, Medium or Low category for the representative hazard to health and the environment. Where High Hazard chemicals are identified, it is general practice for Prosafe to seek substitutes for these chemicals with lower Hazard chemicals.
We continue to conduct further evaluations to identify safer/greener substitutes in for current high/ medium risk substances.
When a Prosafe vessel operates alongside an offshore installation, it will work within the framework of the host installation’s operating permits. Prosafe and its client’s management systems are cross-referenced within interface documents, and responsibilities are clearly defined.
All Prosafe vessels are subject to Maritime requirements (MARPOL) and have implemented a waste management system (Garbage Management Manual). The manual includes assessments of all potential waste products originating onboard together with the requirements for waste segregation for transportation ashore.
Prosafe actively manages all locally produced waste at our sites. We also track and monitor the performance of our third party waste disposal company in their handling and disposal of all waste that has been transferred to them by Prosafe.
Ballast water management for our vessels is controlled within the confines of the International Maritime Organisation (IMO) regulation.
Our vessels have International Ballast Water Management (IBWM) certificates. These certificates are all issued under the International Convention for the Control and Management of Ship’ Ballast Water and Sediments and are subject to periodic survey.
Discharge of sewage
Sewage discharge is controlled within the confines of IMO regulations. All vessels within the fleet have been subject to International Sewage Pollution Prevention (ISPP) surveys and have been issued certification in accordance with MARPOL Annex IV by the relevant Flag.
