propulsion systems, which mainly run on boil-off
gas from the LNG cargo. When natural gas is cooled
down to its liquefied state at minus 160 degrees
Celsius, a certain amount of the LNG will naturally
re-gasify into its gaseous state (boil-off gas). The
boil-off gas is produced at a rate dependent on the
outside temperature and the level of filling of the
tanks and can either be reliquefied into LNG or used
as fuel for propulsion of the vessels. Due to the cost
and energy needed to power a reliquification process
plant very few vessels are outfitted with such plants.
The boil-off gas is thus used for propulsion, which
makes sense both economically, as natural gas is
significantly cheaper than oil-based alternatives, and
also environmentally, as natural gas is a considerably
cleaner fuel than oil-based alternatives. Compared
to oil-based fuels, natural gas emits 10-20 % less
greenhouse-gases, virtually zero SOx and particulate
matter and 90 % less NOx.
As LNG vessels carry regular bunkers for ballast
voyages the potential for major environmental
accidents mainly relate to the risk of a ship suffering a
breach and subsequently leaking substantial amounts
of bunkers oil into the environment.
The last potential impact is waste produced by the
vessels, discharge of untreated ballast water and
potential spills of chemicals, bilge water and sludge
etc. into the environment. Discharge of untreated
ballast water may potentially introduce non-native
organisms into marine environments worldwide.
Company policies and objectives
Based on the long-term goal of environmental
excellence, and as set out in the Company’s
Safety Management & Environmental Protection
Policy, Awilco LNG works toward minimising the
environmental impact from its vessels with the goal
of zero spills. The Company has adapted a zero-
tolerance policy towards:
• Spills to the environment
• Emissions of ozone depleting substances
• Unauthorised disposal of garbage or waste to the
marine environment
Additionally, Awilco LNG aims to minimise as far as
practically possible the emission of CO2, NOx and SOx
from combustion engines, boilers, incinerators and
emissions from cargo and fuel oil tanks and systems
through evaporation.
Awilco LNG shall adhere to national and international
environmental laws and regulations, and constantly
promote best practices identified within its own
operations and the industry to improve our impact on
the environment.
How we achieve our objectives
Our objectives are operationalised in the Company’s
Safety Management & Environmental Protection
Policy. The objective of this policy is to ensure
that the Company gives the highest priority to the
environment through the following measures:
• Provide support to ships' operation by
implementation of a well-structured Safety
Management System (SMS) based on a well-
defined management organisation. The SMS is
an integral part of all our activities and includes
instructions and procedures which contribute
to the highest safety standards onboard our
ships, ensuring that cargo is handled correctly
and preventing situations which threaten the
environment. The SMS is based on national and
international requirements and standards for
quality and safety, including the ISM code and the
TMSA issued by OCIMF
• The management system of the fleet is certified
according to ISO 14001 and ISO 9001
• Operate the vessels with continuously properly
trained, informed and motivated crews
• Provide, equip and maintain the ships to the
necessary standard as required by national
regulation and international convention. Both
WilForce and WilPride are fitted with ballast water
treatment systems.
• Establish contingency plans and execute drills and
training to improve emergency preparedness to
meet situations which represent dangers to life,
health, environment, ship and cargo
• Implement and maintain a safety management
culture within the Company
• Use a reporting system for accidents, near
accidents, non-conformities and improvements,
with special attention to the learning effect
through feedback of experience and suggestions
for improvement
• Antifouling paint systems with lowest resistance
