The Harris Pye Engineering Group is currently engaged in turnkey scrubber installation packages for major cruise line companies. On 3rd August 2016 Harris Pye completed the installation of an Advanced Emission Purification System, fully automated, which was duly DNV GL certified which met with MARPOL regulation 14 of Annex V1 for the control of emissions complying to regulations 14.1 or 14.4.
The design package for open and closed loop systems was utilized to model and fabricate all piping systems, hardware integration, and major/minor steelworks. Along with new exhaust tail pipes, sea chests were installed with the vessel in service along with the associated overboard discharges. A new decorative funnel extension was designed, fabricated and installed to encapsulate the scrubber tower, and newly constructed Technical Room which houses the AEP Hybrid components. To accommodate the operating fluid systems correctly sited new tanks, together with on-board conversions to existing tanks, were engineered and fabricated with special coatings applied. Electrical power, distribution and automation systems was installed by Harris Pye experienced electrical/E&I staff.
Harris Pye is currently installing similar systems on other large cruise vessels with completions imminent and throughout the year.
The installations currently under way and already installed are in response to the need to reduce Sulphur Oxide (SOx) emissions from fuel oils and the recent implementation of more stringent rules within Annex VI of the 1997 MARPOL protocol on 1st January 2015 which have seen SOx emissions significantly reduced to 0.1% in Emission Control Areas (ECAs). On 1st January 2020, a new regulation will enter into force limiting the Sulphur emissions for vessels to 0.5 % in other designated areas, making it crucial for ship owners to ensure proactive, effective planning and groundwork is in place to comply with these regulations.
“Not surprisingly, we are seeing a marked increase in interest in complete turnkey installation packages for exhaust gas scrubber systems; from initial site surveys, feasibility studies, 3D laser scanning/modelling ultimately progressing to detailed engineering and design, leading to a cost effective installation programme,” explains Harris Pye’s Chief Technical Officer, Chris David.
“With workshops in the UK, Middle East, Asia and Brazil, we can offer an efficient and economical alternative to onsite production through prefabrication prior to installation, thereby reducing installations costs and disruption to a ship’s itinerary. All our workshop facilities are compliant with the following standard certifications: ISO 9001, API QI, ASME S.R.U Stamps, GL Workshop (welding) and EN 1090 Execution Class 2.”
“Vessel owners are able to benefit from local and globally discounted supply chain costs and reduced installation times. Harris Pye Engineering workforce includes fully versed, certified and accredited skilled workers for both GRE, GRVE and conventional steel piping, all managed by dedicated project management teams liaising and coordinating with vessel owners on a daily basis to ensure seamless and efficient installations.”
