Vessel of Concern Risk Assessment Methodology

The objective of this presentation is to provide an update of the Vessel of Concern Methodology used to assess abandoned, derelict and wrecked vessels in Canada.
Abstract

The objective of this project was to develop a risk assessment methodology that can be used across Canada to provide a consistent and efficient method to assess the risk posed by vessels of concern (VOC). The risk assessment methodology assesses the level of risk posed by the VOC to the local environment, economy, public safety and socio-cultural impacts, including impacts to Indigenous Communities. The risk assessment has five different phases that are used to assess the risk posed by the vessel. A GIS-based tool was also developed to assess the VOCs in the field and provide a real time evaluation of the risk score. This presentation will describe the risk assessment and the scoring tool.

Challenges in Assessment of Harbour Waves
Zhenyong Yang, GEMTEC Consulting Engineers Ltd.
The objective of this presentation is to discuss how wave agitation is a key factor in port planning and design. Case studies will be used to demonstrate the challenges in assessments of waves in harbour area.
Abstract

Wave agitation is a key factor in port planning and design. To assess wave conditions in the harbour area, a numerical model has been widely used and has been recognized as a reliable tool to predict waves in the harbour area. However, wave problems can be complicated. For example, when waves penetrate the harbour area the wave energy in the harbour basin can be reduced due to breakwater sheltering or wave diffraction. However, wave agitation can be caused by unusually long waves, wind waves, or reflection from harbour structures, etc.

Long waves may be significant in ocean faced coastal harbours. If it occurs in the harbour, it may cause large boat movement and the wave agitation can be much worse than expected. Harbours in Denmark, Mauritania, and Taiwan will be discussed.

Wind waves are usually not a big issue for large commercial vessels. However, frequent wind waves can be a significant hazard to small boats in fishing harbours or marinas. In this case, a fishing harbour in Qatar will be discussed

Wave reflections from structures can cause unexpected reflection and very bad consequences to the harbour structures or boat operations. A marina in Abu Dhabi and a fishing harbour in the Bay of Fundy will be discussed.

In this presentation, numerical models will be used to demonstrate the problems in each case.

Design and Construction of Jetty November Juliette (NJ), Halifax, NS
Lorne Oram, Department of National Defence
The objective of this presentation is to showcase the design and construction of Jetty November Juliette (NJ) in Halifax, NS, in support of the Canadian Arctic Offshore Patrol Ship program. Key challenges including navigating the lines between Federal and provincial justification, stakeholder engagement, subsea blasting, and environmental considerations will be explored.
Abstract

Infrequently does Canada add an entirely new class of warship to its Defence arsenal, and recently the Government of Canada did just that, embracing a new class of vessel with its Arctic Offshore Patrol Ship (AOPS) program. This program speaks directly to the government’s mandate for preservation of Arctic presence and sovereignty of our northern nation.

As a plane needs a hangar, a warship needs a berth, to establish readiness as it meets its call for operations with the Department of National Defence (DND). The AOPS vessels are being constructed by IRVING at its ocean-side facility adjacent Her Majesty’s Canadian (HMC) Dockyard in Halifax, Nova Scotia, which will also serve as a berth for the AOPS vessels as they emerge off the line starting in the summer of 2019.

The berth for the vessels will be Jetty NJ, which has been under design and construction for several years, reaching substantial completion in summer 2019. While a new construction, this is hardly a new jetty space, but is rather laden with history in the Canadian military. The space occupied by Jetty NJ was formally part of wartime construction process in Halifax in the late 1940s, and offered two berths at that time – Jetty NJ and NK. Being of traditional timber pile construction, these jetties, while having served well, met their life expectancy and were deemed unsafe and subsequently demolished in January 2004. The space was later envisioned to berth the new Joint support ship (JSS), however, later became established as the future multi-purpose berth for AOPS vessels, where they would reside in a 2x2 configuration.

NJ was designed several years ago in Dartmouth, Nova Scotia. A modern jetty requires not only a space to tie up, but also numerous services such as water, steam, and wired communications, all fed via subsurface tunnel systems. In the case of NJ, a new high voltage feed and substation was also required.

The tender for construction took place in 2015, being awarded in June of that same year. This was the most significant undertaking of marine construction by DND in quite some time. It went very well, and, like most construction projects, was met with interesting challenges. The project experienced acute intersections in the domains of provincial environmental regulations on sodium, the realities of effects on marine habitat and aquatic life (lending to compensation), and the impact of subsea blasting to the local community when it quickly garnered awareness to a portion of residents of the Halifax peninsula. To meet these challenges, a plethora of stakeholders were involved and the project demanded strategic planning, foresight, and a refined approach to communication and collaboration among all parties. These elements were paramount in realizing the successful delivery of Jetty NJ in 2019, having surmounted all challenges.
